At the Heartland plant there are multiple short bed GMC pickups in the parking lot, I'm guessing for Heartland use. Guess that says something.
I did put a superglide in my truck, but that was during the "getting ready to buy a 5th wheel trailer" mode time frame.
We originally were ready to make a deal on a 3 year old never used SB toy hauler, which would have required a slider.
My truck was ready for the trailer before we even bought one. I had gone to Indiana to look at the big 4 toy haulers, SB, KZ, Heartland and Keystone.
Don't know if I will need it or not with the Cyclone, but it is there and is staying.
BTW - with a Superglide hitch you absolutely cannot go past 90 degrees. You will damage the hitch and cause a failure.
I am expecting that I may have a need for the slide just getting into my driveway. Although I frequently can just turn around n the cul-de-sac and back straight in, occasionally I have to back in on a angle, and my driveway is a little steep.
So my thoughts are when the trailer back end is going uphill and the front of my truck is still a little nose high the extra room the slide offers will keep the upper part of the trailer away from the cab.
